Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-N-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl][4-(4-fluorophenyl)piperazin-1-yl]methylidene}hydroxylamine (CAS 320420-31-3), a certified reference material (molecular formula C17H15ClF4N4O, MW 402.77 g/mol) for analytical method development and quality control.
Structurally, (E)-N-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl][4-(4-fluorophenyl)piperazin-1-yl]methylidene}hydroxylamine (C17H15ClF4N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 402.77 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
